Iv been having so many problems Iím ready to do an insurance claim. Anyway on my ******d 12 with ppei tunes and 126k miles I have developed a random white/grey haze at idle. When I punch it itís greyish then black and fine until I let idle for 5 or more mins.

Also I noticed when truck is in park or neutral there is a slight dry bearing noise coming from the front of the trans. If I put it in gear or reverse the noise goes away. Itís not very loud but Iím very picky with small noises. Is this something I should be worried about?

Truck runs awesome except for my shifting and tune revisions Iím dealing with but thatís a different problem. All fluids stay the same level and temps all look normal. Kind of freaking out and donít know what else to look for. Any help would be greatly appreciated

Just a hunch, but the front of your transmission is near the back of your turbo, It isnít a fun job but I would consider checking the turbo for shaft play. Especially since it is a 2012, the bearings are known to go out and when they do it will smoke white smoke at idle. In fact, mine just did this but I let it go too long and the bearings blew apart and the shaft broke in half, fix it before that happens.

Also, if it is the turbo I would recommend getting the 2015 upgrade so this doesnít happen again.
